Abstract
The invention relates to an ABS melt gate. The ABS melt gate comprises a main runner and a gate, and is characterized in that the gate is a point gate, and a certain inclined angle is formed between the ridge of the vertical section of the main runner and a perpendicular direction. According to the ABS melt gas provided by the invention, the main rubber adopts a reducing structure, so that the speed and the flow speed of ABS injection are increased; the taper of the gate is also different from that of monochromatic injection, so that the jet power of the ABS injection is further increased. The ABS melt gate disclosed by the invention is simple in structure and can effectively meet the requirements for ABS bicolor injection.
Description
Technical field
The present invention relates to a kind of ABS melt cast gate, belong to injection molding technology field.
Background technology
In double-shot moulding, ABS is common used material, owing to adopting the injection moulding respectively of two kinds of injected plastics materials, compared with homogenous material injection moulding, has certain special requirement to the version of cast gate and sprue.
Summary of the invention
For above-mentioned, the object of this invention is to provide a kind of ABS melt cast gate, sprue adopts tapered configuration, to increase speed and the flow velocity of ABS injection moulding; Cast gate tapering is also distinguished to some extent with monochromatic injection moulding, sprays dynamics to increase ABS injection moulding further.
For achieving the above object, the present invention is realized by following technological means:
A kind of ABS melt cast gate, comprise sprue and cast gate, it is characterized in that: described cast gate is spot pouring mouth, crest line and the vertical direction of described sprue vertical section have certain angle.
Further:
Described a kind of ABS melt cast gate, is characterized in that: the crest line of described sprue vertical section and the angle of vertical direction are 2 °.
Described a kind of ABS melt cast gate, is characterized in that: the crest line of described spot pouring mouth vertical section and the angle of vertical direction are 25 °.
Described a kind of ABS melt cast gate, is characterized in that: the diameter of described sprue and spot pouring mouth connecting portion is 2mm.
Described a kind of ABS melt cast gate, is characterized in that: described pin-point gate nozzle diameter is 0.5mm.
Described a kind of ABS melt cast gate, is characterized in that: described spot pouring mouth length is 2.5mm.
The invention has the beneficial effects as follows: a kind of ABS melt cast gate provided by the invention, sprue adopts tapered configuration, to increase speed and the flow velocity of ABS injection moulding; Cast gate tapering is also distinguished to some extent with monochromatic injection moulding, sprays dynamics to increase ABS injection moulding further.Structure is simple, effectively can meet the requirement of ABS double-shot moulding.
